Not only do I have the cardigan version, but I also own 2 vest versions. And as a nice, easy project, I whipped myself up a third! Just call me the Queen of Drapey. :)
Happy with my long flowy, drapey vest!
This is Butterick 4989 in View C, the long drapey one. This is labeled a 2 hour pattern, and I'd say that's pretty accurate. It was very simple, only 2 pattern pieces; the back and the front is cut twice. I was a little slower, but I didn't work straight and I had some self-created issues with the fabric layout. I was a bit short on fabric, so I studied the directions seeing if I could squeeze out some more fabric. Then I noticed that the pattern includes a 4 inch hem. Wow. You do NOT need a 4 inch hem. I figured I was 9 inches short, so I cut 3 inches off each pattern piece and barely squeezed this out. But as you can see, I still have tons of length, so I wouldn't stress out about the fabric requirements.
Obligatory back shot.
The fabric is really pretty. It's a sage green stretch lace that has some shine to it. It's really bunchy (as in bunches up a lot) and it has a lot of holes (because duh, it's a lace) which made it tricky to sew, but not as difficult as I thought. I was able to use a normal needle and everything, just used a zig zag stitch. But as a result, this didn't come out as particularly neat in terms of construction as it would've in a simpler fabric. But because the lace is a little busy, you really can't tell.
A close up shot of my lace, although the color is more accurate in the other pictures.
Overall, I highly recommend this pattern and I am very happy with the result. :)
